Brett Favre

Jerry Lai-US PRESSWIRE, US PRESSWIRE

Perhaps the king of un-retiring, Brett Favre has waffled between whether to retire or not retire numerous times. In 2008, he came out of retirement to play for the New York Jets, and the following year he retired only to come back with the Minnesota Vikings. In 2010 teammates Steve Hutchinson, Ryan Longwell and Jared Allen flew down to Mississippi and convinced Favre to un-retire during the 2010 season. Favre is currently retired, for now.
